Sarri joined Chelsea last July as a replacement for fellow Italian Antonio Conte after spending three years at Napoli.

He guided the Blues to third in the Premier League and won the Europa League, but still endured a tough campaign at Stamford Bridge with fans not convinced by his style of play.

Chelsea said Sarri wanted to return to Italy to be nearer his family, including his elderly parents.

Chelsea director Marina Granovskaia said: "In talks we had following the Europa League final, Maurizio made it clear how strongly he desired to return to his native country, explaining that his reasons for wanting to return to work in Italy were significant."
